Why It's Never Okay to Drink Alcohol While Pregnant, Seriously

Drinking During Pregnancy Leads To Fetal Alcohol Syndrome (FAS)!

Is it ok to drink alcohol during your pregnancy? You all know the answer….NO! Drinking during pregnancy is simply not worth the risk. Yet, many women around the world continue to drink during their pregnancy. Approximately 9.8% of pregnant women globally consume alcohol during pregnancy; the majority of which are European, North American, Russian and Australian (7). What effect does alcohol have on a growing fetus? What are the consequences of drinking alcohol during pregnancy? This article presents the science behind alcohol consumption during pregnancy and how it leads to fetal alcohol syndrome. fetal alcohol syndrome

Fetal Alcohol Syndrome And Fetal Alcohol Spectrum Disorder

Is any amount of alcohol acceptable during pregnancy? The answer is NO! Alcohol is the only culprit in fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorder (FASD). FAS and FASD produce a wide variety of debilitating symptoms such as (8,9):
  • Permanent brain damage
  • Prenatal growth restriction
  • Postnatal growth restriction
  • Congenital anomalies
  • Deformed facial features
  • Chromosomal abnormalities
  • Cognitive impairment leading to:
    • Behavioral issues
    • Mental health problems
    • Decreased ability to process linguistic, auditory and visual information

Alcohol Is A Teratogen

Alcohol is a teratogen, a compound that can easily transfer from the mother to the fetus through the placenta. The consumption of alcohol while pregnant can cause life-threatening damage to the nervous system/internal organs of a developing fetus, leading to the following pregnancy complications (2,3,5,6):
  • Stillbirth
  • Spontaneous abortion
  • Premature birth
  • Intrauterine growth retardation
  • Low birthweight

FAS/FASD And Mental Health

The neurological damage caused by alcohol leads to FAS/FASD.  A condition that not only causes physiological harm and developmental problems in newborns but also causes secondary lifelong impairments.  In most cases, the secondary impairments of people with FAS/FASD experience throughout their lives come from an inability to develop into a psychologically mature adult. People with FAS/FASD are more likely to experience the following throughout their lives (10):
  • Academic failure
  • Mental health problems
  • Inability to live independently
  • Substance abuse
  • Trouble with law enforcement
  • Difficulty maintaining employment

What Factors Influence The Likelihood of Developing Fetal Alcohol Syndrome?  

Although alcohol consumption has a high chance of causing detrimental consequences to the outcome of a pregnancy, not every woman who drinks during pregnancy will have a baby with FAS/FASD. This is because pregnancy comes with a level of uncertainty. The mother and fetus may have genetics that reduces the teratogenic effects of alcohol, they may be in a highly supportive environment for a healthy pregnancy, they may have very low-stress levels that mitigate the neurological damage alcohol can cause, the mother can have an excellent nutritional status before and during the pregnancy that reduces the negative consequences of drinking alcohol on fetal development, and the lifestyle of the father also will have an influence on the effects of alcohol during pregnancy due to the genetic quality of his sperm (1,4).

Take Aways

You knew before reading this article; you shouldn’t  be drinking alcohol if you are pregnant. Hopefully, you now have a greater understanding of how consuming alcohol during pregnancy will lead to harmful outcomes for your child. Developing embryo’s are overly sensitive to the teratogenic effects of alcohol, and drinking alcohol during pregnancy can have detrimental consequences for newborns. During the first stages of pregnancy, the growing fetus is most susceptible to damage from alcohol and other harmful substances. If you are looking to become pregnant, we recommend cutting alcohol out of your diet completely until your pregnancy is over.
